摘要
利用傅立叶变换对一组从审计记录中获得的离散数据进行处理,介绍了选择傅立叶变换的系数的准则,它用来从一组系数中寻找出一个统一的标准值;并用这个值与一个门槛值相比较,以决定是否有异常情况发生,同时给出了一些测试结果。
A set of discrete points obtained from audit, records on a behavior session are processed with Fourier transform. The criterion of selecting Fourier transform coefficients is introduced, and is used to find a unified value from the set of coefficients. This unified value is compared with a threshold to determine whether the session is abnormal. Finally test results are reported.
